INVEINTOR Patented May 12, 1931 r'rsn'r EUGENE E. MCWAEN, OF L ANGELES, CALIFGRNIA TILE TEAKING ATTACHMENT TO VIBRATII'TG ll'JZACI-IENES Application May 5,

This invention relates to improvements in brick and tile making machinery and more particularly to a type of brick making machinery employing the principle of vibration 5 in producing bricks, tiles and the like.

One of the objects of this invention is to provide a simple, eflicient and inexpensive device of this character wherein interchangeability of instrumentalities for making either 19 brick or hollow tile is attained economically.

Another object of this invention is to bring about an improvement in a type of brick making machinery disclosed in a former patent issued to myself, Patent No. 1,574,985, wherein a mounting for a vibrating machine is described. This former machine was adapted for making brick, and a similar machine was needed with some changes in construction of the formers, for making hollow tile; thus requiring two separate distinct machines. My present invention aims to do away with the necessity ofproviding two distinct machines for interchangeably making brick or hollow tile and in the present machine means are provided in the form of a removably mounted frame with a core box and other attaching parts for converting the brick making machine into a hollow tile making machine.

Another object of this invention is to provide a device wherein the brick forming atbrating type are designed to be removed from the machine and in place thereof another at tachmcnt placed on the machine particularly designed for the purpose of making mollow tiles quickly and efliciently.

A still further object of this machinery is to provide a quickly detachable mounting for use in connecting with a vibrating machine that admits of simply changing over from a brick making former to a tile making former, without disturbing the other adjacent parts of the vibrating machine. The arrangement is such that after the necessary changes shall have been made the vibration of the mountings on the legs of the machine will continue while the material in the core boxes are being placed around the plungers forming the holes in the tiles.

lVith the above and other objects in View my invention consists in the combination, arrangement and detaiis of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings wherein similar reference characters designate similar parts throughout the respective views,

Figure 2 is a vertical elevation, partly in section, of the machine adapted for making hollow tiles,

Figure 8 is a top plan view of the core box used in connection with my invention, and

Figure dis a cross section taken thru a tile made by this machine.

The parts of my vibrating mechanism used in connection with this machine are described in Letters Patent No. 1,574,985. At the lower ends, 12a, of the leg portions of the machine are mounted base flanges A, to the underside of which are secured rubber mountings B to the under side of the latter of which are secured disks A. Upon suitable brackets or bearings 31 having the top portions 32 are mounted vibrating-causing wheels 32 whose shaft 33 is journaled in suitable bearings; these wheels 35 carry eccentrically mounted weights 34 the shaft being designed to be rotated by motor driven connections (not show lVhen the motor is started and shaft begins to rotate the wheels 35 are set in motion and the weights 34 shifting their positions in making their cycle a vibrating motion and action is imparted to the legs of the machine which having the rubber mountings B cause the entire machine to vibrate, thus causing the plastic material or the like in the brick making formers or mold or core boxes to settle in a manner similar to being tamped from overhead.

The machine described is designed for making cement bricks and is not suitable without changes for the making of hollow tile. To adapt such make of vibrating malit chine to making hollow tile is the purpose of certain parts forming a removable attachment to the machine already described.

The upper part of the machine is preferably hollow and the upper portions of the legs of the machine may flare outwardly as at- 37. The first part of my attachment consists in a top plate 38 which overlies the top portion of the machine, being removabl y bolted to the machine by means of the fasteners 40. This plate formed with a plurality of openings (not shown) for the reception. of the plungers hereinafter described.

This plate serves to provide a mounting for the other parts of: my atta ':hment as follows. I also provide a holder plate in the form of a box-like member 42 having a perimeter flange 42 designed to snugly lit the raised portion 4.0 of the plate l as shown clearly in Figure 2. This plate is also formed with the openings necessary to receive and accon'nnodate the plunger-s 43 carried by a horizontally disposed slide i l to be further described hereinafter.

The holder plate receives in surmounted position the core box 56 illustrated particularly in Figure 0; 57 designates the side raised walls of the rectangular frame of the core box while G designates a plurality of plunger receiving holes, two in number; said holes G being arranged in pairs, each pair being located in one of four separate core box sections designated E, C, D and F respectively. By means of any suitable fasteners the core boxes are designed to be removably registered with respect to the holder or pallet 42.

The hole forming plungers 43 are mounted on the slide 44:, and the latter carry spaced lugs 47 extending in the right direction to receive therebetween the fulcrum pin 48 to which the connecting rod 48 is attached. The lower end of the connecting rod 49 is pivoted by means of the pin 51 to the crank arms 50 carried by the sleeve 52 secured upon the shaft 53 mounted in the bearings f secured upon the legs 11a of the machine. It will be understood that the bearings 54 will be so mounted that shaft and cranks will be out of striking distance of vibrating weights 34, or of the vibrating mechanism. The frames 31, could be mounted at right angles to shaft 53 if desired. This shaft carries the crank arm 54? to which an operating handle 55 is secured and by means of which shaft 53 is rotated to operate the crank arms 50 to cause the slide 44 to be movably guided in four guides of any approved construction, two of said guides being shown as at 6 having the track grooves 45 in which the corners of the slide it slide when actu ated.

Figure 4 shows the kind of hollow tile which is made by means of the machine having the attachments described. In oper ation the pallet plate 4-2 is laid upon the top plate 38 so as to register therewith. The core box is next mounted in registering position upon the pallet plate or holder; the holes in all of these parts will now register.

The handle 55 is now turned around by the operator so as to rotate the shaft 53, to cause the former slide 44 to move upwardly to cause the plungers 43, of which there are as many as there are holes G in the core box, to move upwardly so as to project thru the corresponding openings in the plate holder 4-2 and core box 56. l/Vith the parts ren'iaining in this position, cement is now taken and placed in the core box around the plunger-s with a surplus of cement above the top edges of the core box. The motor of the machine is next started and thereupon the entire machine begins to shake and vibrate furiously, causing the cement in the core box to gradually settle, being pressed down by the vibratory motion of the machine under influence of gravity. Finally when the operator finds that the cement has been packed adequately in the core box, he stops the motor, and takes hold of crank handle again and lowers the plungers 4-3 out of the holes in the core box, pallet holder and top plate 38. He then unhooks the core box from the pallet; or he may simply lift the holder with surmounted core box from the machine and set it aside for the cement in the core box to harden and set; he next proceeds to lift tlui core box from the pallet; by using another pallet with the same core box or with another core box the same operation may be repeated for the purpose of making four more tiles as shown in Figure 5.

When it desired .to make brick again, the top plate 38 with the surmounted holder 42 and core box may all be removed from the top portion of the machine so that proper brick making attachments may be employed for the purpose. It will thus be seen that the machine can be adapted interchangeably for making brick or hollow tile with great facility and that the cost of making brick or hollow tile considerably reduced, while it is possible for one operative to turn out a greater output of brick and tile per working day than was heretofore thought possible. I do not intend to restrict myself to the exact details of construction disclosed but intend to cover all variations falling within the purview of the appended claims.

Vhat I desire to claim and secure by Letters Patent is 1. In combination with a brick making machine an attachment mountable upon the top portion thereof, and consisting of a top plate, means securing the top plate removably upon said frame, the main body portion of said top plate being raised, a holder having a socket into which the raised portion of said top plate projects, a core box removably registered upon said holder, said top plate, holder and core box having a series of alining holes, and means retractably mounted beneath the top of said frame and designed to project plungers thru all of the alining holes for the purpose of providing the holes of hollow tiles. 2. In combination, a base plate having means of attachment to a vibrating machine, a rectangular block raised above the baseplate, a. rectangular holder having a marginal rectangular rim enclosing said block snugly so the holder overlaps the base plate, the base plate and holder having registering holes, a. rectangular core box open at the top and bottom but resting upon the holder so the latter forms a bottom for the core box, division partitions on the core box surrounding groups of said holes, and means for hooking' the core box onto the holder to attach it in position.

In Witness whereof he has hereunder set his hand this thirteenth day of March, 1928.
